  • Mitsubishi develops innovative antenna system called SeaAerial!

The system shoots seawater into air to create conductive plumes for transmission of radio waves.

Today Mitsubishi Electric Corporation made a very important announcement from Tokyo. Mitsubishi has developed an innovative antenna system called the SeaAerial.

The system shoots a column of seawater into the air to create a conductive plume. The plume is used for the transmission and reception of radio-frequency waves.

SeaAerial can be easily implemented both offshore and along shorelines. The system is believed to be the first ever of its kind.

SeaAerial is capable of receiving digital terrestrial broadcasts for normal viewing. Mitsubishi wanted to develop an antenna practicality so they used seawater. Seawater is the most abundant resource on Earth

To use the plume of seawater as an antenna it needs to be insulated. For this purpose Mitsubishi Electric developed an insulated nozzle. The nozzle transmits radio waves to the antenna.

The transmission occurs even when the plume is physically connected to the sea surface. The nozzle is effectively insulated using a quarter-wavelength tube. The tube is placed inside the nozzle. 

To secure antenna efficiency Mitsubishi Electric used simulations. The simulations determined the ideal diameter of the plume which determines efficiency.

As a result the antenna has an efficiency level of 70 percent. Similarly the operating frequency is determined by the size of an antenna. Even with a large size, the SeaAerial can be installed anywhere on the shore.

The SeaAerial only requires a pump and an insulated nozzle so it can be easily shipped and moved. The antenna by Mitsubishi offer new functions and superior performance.

Mitsubishi is also further looking into investigating conductive and trans-mutative liquids. For new materials for their antennas.
